Hey guys, my first post post here
I have a problem with my beloved CBR that I cannot seems to solve by myself. Starting from the beginning, the downpipe of the bike started to rust, and at one point it snapped completely. I have bought a replacement downpipe, fitted and sealed it in the place, but now the bike kind of lost its 'power' (yes its a 125, still fun to ride, gotta learn on something and this bike is most reliable 125 I've ever been on).
Before anything was broken the bike was able to pull 75-80mph only struggling with acceleration at 6th gear between 6-7k revs. Now after fitting the new downpipe (replacement of a stock pipe, with no restrictions according to the shop) thebike struggles a lot - in any gear goes up to 5-6k revs and almost stops accelerating although the revs go up. I can also feel with my hand that when in neutral I open up the throttle the revs go up steadily, but when it hits around 6 the pressure of gas coming out of silencer kind of drops (just like when you blow the air with your mouth and run out of air). Also the top speed dropped to around 50-55mph max in 4th gear (5 and 6 just make it slow down).
Is there anything i can do with this pipe (drill it or something)? I cant really afford another one, and I really need and want to ride the bike
Thanks in advance guys...
